Title: Self-alignment type semiconductor laser with window and manufacture thereof
Inventor: KOMAZAKI IWAO
IPC: H01S5/20
Filed: 1989-06-13
Abstract: PURPOSE:To achieve a large-output semiconductor laser by providing a current block layer on the side surface of a mesa and then connecting an active region and a window region in taper shape. CONSTITUTION:Only an active region is covered with a resist 20 and the epitaxial crystal surface is exposed only for 50mum long window region at each 300mum interval in forward mesa direction, thus eliminating an active layer 3 completely. Then, the resist 20 is eliminated completely and a p-type light guide layer 8, an n-type current block layer 9, and an n-type current block layer 10 are embedded on the entire surface. Only the window region is covered with resist, the active region is eliminated until the inside of a p<+> type cap layer 5 by a phosphoric acid etching liquid, and the window and active regions are flattened. SiO2 is formed on the surface of a wafer and 6mum wide striped- shaped SiO2 film 21 is left in inverse mesa direction. A p-type clad layer 4 is left by 0.3-0.4mum in thickness on both sides of mesa stripe. Regrowth is made with the SiO2 film 21 being attached to, an n-type current block layer 11 is allowed to grow selectively, and both sides of mesa stripe are embedded.

IPC: G06F17/17
Filed: 1989-06-14
Abstract: PURPOSE:To attain approximation to a value more accurate than a simple proportion calculation by approximating a broken line graph of Zc (Za<Zc<Zb) with the broken line graphs of Za and Zb and then calculating Y from X and vice versa. CONSTITUTION:A broken line graph of Za consists of (i) pieces of dots Pai (Xai, Yai), and Xa1<Xa2<...<Xai is satisfied together with Ya1<Ya2<...<Yai respectively. A broken line graph of Zb consists of (j) pieces of dots Pbj (Xbj, Ybj), and Xb1<Xb2<...<Xbj is satisfied together with Yb1<Yb2<...<Ybj. Furthermore a broken line graph of Zc to be approximated consists of (k) points of Pck (Xck, Yck) where Xc1<Xc2<...<Xck and Yc1<Yc2<...<Yck. Then a ratio R = (Zc - Za)/(Zb - Za) is calculated between two broken line graphs, and the combination of two dots most approximate to each other is detected. Thus it is possible to obtain the approximate value with higher accuracy.

Title: Drill
Inventor: WAKIHIRA KOICHIRO
IPC: B23B51/00
Filed: 1987-06-17
Abstract: PURPOSE:To enable accurate perforation by forming a sub-groove in such a way that a secondary cutting edge is positioned on the thick-wall part side of a drill from a straight line connecting the sub-groove side end of a main cutting edge and the end of outer periphery on the sub-groove side of a chisel edge. CONSTITUTION:A sub-groove 4 is formed in such a way that a ridge line which is the edge of a secondary cutting edge 1b is positioned on the thick-wall part 6 side of a drill 10 from a straight line connecting the points on each cutting edge line of the sub-groove side end of a main cutting edge 1a and the opposite sub-groove side end of a chisel edge 3. Thereupon, the drill 10 having thus formed end parts will have a fairly shorter chisel edge 3 than the chisel edge of a drill having no sub-groove 4, improving the biting property into a workpiece while making it hard to cause a walking phenomenon. Accordingly, the rotation center of the drill 10 can be effectively prevented from moving, reducing cutting resistance while improving a cutting property to carry out accurate perforation.
